Systematic Colour (Part 1): An Introduction to Colour Theory
Notes from lecture:
Colour hugely impacts our ability to read a piece of text.
Yellow on black is the greatest contrast - it's often used in warning signs so a warning is what yellow/black is recognised as.
Colour perception is physical - physiological - psychological. Rods in the eye convey shades of black and white, cones allow the brain to perceive colour. One cone sees red/orange light, one sees green light and another is sensitive to blue/violet. If a single cone is simulated, we see that colour. Because of this, the eye can be fooled through the proportionate adjustment of three colours.
CMYK (black is key) - halftone dots - print - subtractive colour
Systematic Colour (Part 2): Dimensions of Colour
Hue = one colour
Colour = one or several hues
“Colour" + “Hue" are often interchangeable terms
"Chroma" refers to all colour including shades, tints and tones
Chromatic Value = Hue + Tone + Saturation (Luminance)
Intensity, saturation and brilliance are interchangeable terms that relate to higher or lower degrees of vividness due to diluted or undiluted colour or pigmentation
Shades are hues plus black
Tints are hues plus white
Tones, meanwhile, are hues plus grey
Colours can look completely different when they’re paired with others.
PANTONE
Universal colour identification system
Universal colour identification system
Coated: glossy stock, something with a sheen where the ink sits on paper
Uncoated: more porous stock, more muted which ink sinks in
Colour in design has to be systematic.
